A wall range including an open front cabithe frame 4. countersunk in the front of the net mounted in the wall, a frame imbedded in closure 6 is a panel 8 of suitable material. the wall and surrounding the front edge of the 50 The closure 6 is substantially filled with a suitcabinet, a cooking unit hingedly mounted at the able heat insulating material 9 over which a lower edge of the cabinet to close the latter and cover plate I0 is provided. Electric heating units comprising a closed casing filled with insulating II are mounted on the inner side of the closure material and adapted in the closing position of 6. Also mounted on the hingedly mounted clo the unit to project into said cabinet, and elec- 55 tric heating unit countersunk in the top of said casing and into said material, a plunger type switch mounted in said wall behind the top of said frame and having an inwardly movable plunger normally extending through the latter, a flange on said casing engaging said plunger in the closing position of said container to move said plunger inwardly, and a flexible cable connection between the switch and unit extending from said switch to said wall and cabinet and into said casing and insulating material.

2. A combination of the character described comprising a cabinet, a closure for the front of said cabinet and hingedly secured thereto along one of its longer edges, a flange encircling said closure, a switch mounted in said cabinet and having a plunger projecting outwardly therefrom for breaking contact by engagement with said flange when the closure is in closed position, a

second switch positioned on the outer face of said closure and adjacent said flange, an electrical heating unit mounted on the inner face of said closure and controlled by said switches, and means for maintaining said closure in inoperative position.

3. A combination of the character described comprising a cabinet, a closure hingedly secured to the front thereof along the longer edge, a flange encircling the closure, switches mounted on the outer face of said closure adjacent said flange, electrical heating units mounted on the inner face of said closure and electrically connected with said switches, means positioned upon the hinges of the closure for limiting its movement, and additional means for normally maintaining said closure in inoperative position.
